If C is non-negative, the result of the smax must also be
non-negative, so all sign bits of the result are 0.
This allows DAGCombiner to remove a zext_inreg in the modified test.
This zext_inreg started as a sext that became zext before type
legalization then was promoted to a zext_inreg.

The "#!" line in all scan-build-py scripts were using just bare
"/usr/bin/python" which according to PEP-0394 can be either python3,
python2 or not exist at all.
E.g in latest debian and ubuntu releases "/usr/bin/python" does not
exist at all by default and user must install python-is-python2 or
python-is-python3 packages to get the bare version less "python"
command.
Until recently (70b06fe8a1 "scan-build-py: Force the opening in utf-8"
changed "libscanbuild") these scripts worked in both python2 and
python3, but now they (rightfully) are python3 only, and broke on
systems where the "python" command means python2.
By changing the "#!" to be "python3" it is not only explicit that the
scripts require python3 it also works on systems where "python" command
is python2 or nonexistent.

Prior to this patch, the lowering of memref.reshape operations to the
LLVM dialect failed if the shape argument had a static shape with
dynamic dimensions. This patch adds the necessary support so that when
the shape argument has dynamic values, the lowering probes the dimension
at runtime to set the size in the `MemRefDescriptor` type. This patch
also computes the stride for dynamic dimensions by deriving it from the
sizes of the inner dimensions.

One of the operands of the smax is a positive value so computeKnownBits
determines the result of the smax must always be positive. This allows
DAG combiner to convert the sign extend to zero extend before type
legalization.
After type legalization the smax is promoted to i64 by sign extending
its inputs and the zero extend becomes an AND instruction. We are unable
to remove the AND at this point and it becomes a pair of shifts or a
zext.w.
The result of smax has as many sign bits as the minimum of its inputs.
Had we kept the sign extend instead of turning it into a zero extend
it would be removed by DAG combiner after type legalization.

This patch introduces the abstract base class InlinePriority to serve as
the comparison function for the priority queue. A derived class, such
as SizePriority, may choose to cache the priorities for different
functions for performance reasons.
This design shields the type used for the priority away from classes
outside InlinePriority and classes derived from it. In turn,
PriorityInlineOrder no longer needs to be a template class.

A bit of historical research shows that over the years:
Commit 99efc036 added `pragma comment lib` support for PS4.
Commit fd4db533 added `pragma comment lib` support for all ELF targets.
Commit 1d16515f reworked dependent-library support for all ELF targets.
The upshot is that some PS4-specific code became dead, and the
testing became somewhat fragmented. I've removed the dead code and
combined the previous PS4-specific and linux-specific tests for the
diagnostics into one generic ELF test.
Also added a couple of PS5 runs while I was in there.

Summary:
We use the beginning and end of this enumeration to determine what is
and isn't an object format. The enumeration for the OffloadBinary was
put here by mistake which led to it being mistakenly classified as an
Object file.
This adds new files to track DRs 100-199 and 400-499, but the file
contents are still a work in progress. It also updates the associated
status in the DR tracking page.
These ops complement the tiling/padding transformations by transforming
higher-level named structured operations such as depthwise convolutions into
lower-level and/or generic equivalents that are better handled by some
downstream transformations.

As discussed on the review, this change breaks the standalone
clang build. When building against an installed LLVM, the
LLVM_TOOLS_BINARY_DIR cmake variable points to the location of
the installed LLVM tools, not to the cmake build directory. This
means that we would end up trying to move hmaptool into something
like /usr/bin as part of the normal build, while this should only
be happening when running an install target.
